There is increasing evidence of important cardiovascular effects of aldosterone via classical mineralocorticoid receptors in the heart. Aldosterone plus excess salt administration has been shown to produce both cardiac hypertrophy and cardiac fibrosis in rats. Various clin. studies have reported that aldosterone plays an important role in cardiac hypertrophy; however, the factors that control plasma aldosterone concentrations during angiotensin-converting enzyme (ACE) inhibitor treatment have still not been established. In the present study, we examined the relationship between plasma aldosterone concentrations and the degree of ACE inhibition in 25 essential hypertensive patients treated with an ACE inhibitor. Blood pressure decreased with treatment and plasma ACE activity, estimated in vitro (by a colorimetric method) and in vivo (by plasma angiotensin II/angiotensin I ratio) assay, was suppressed compared with that of hypertensive patients treated with medication other than ACE inhibitors. No relationship was found between the level of ACE inhibition and plasma aldosterone concentrations, which rose in parallel with the duration of ACE inhibitor treatment. The present study demonstrates that continuous ACE inhibitor therapy produces significant suppression of plasma ACE activity in essential hypertensive patients, but that no relationship exists between plasma aldosterone concentrations and levels of ACE inhibition. Plasma aldosterone concentrations tend to increase with the duration of ACE inhibitor treatment, although this increase did not reflect a reduced inhibition of ACE activity.
